SETTING THE CLOCK
After the recessed RESET button has been
pressed the display appears as shown, with
the colon blinking and all the factory pre-set
conditions will be present.

and 'COPY' buttons until the display changes.
To set the clock to the correct time and day, press and release the
button marked PROG. The digits blink. Press the DAY button (the
digits stop blinking) until the correct day number is shown. (1 =
Monday). To change the time quickly in ten minute steps press and
hold down the + or - buttons.
To change the time one minute at a time press and release these
buttons. When the time is correct press PROG to start the clock and
continue setting sequence.
SETTING THE EVENT TIMES & TEMPERATURES
The HP75 can be set by the installer to provide either 2 or 6 events
each day. Refer to the installer setting instructions if this parameter
needs to be altered. Please note that for simplicity the diagrams in this
setting instruction assume that the unit has been set in the “6 events
per day” mode.
The first event (time and temperature) is displayed, together with the
day or days when it is active. Note that the day number(s) displayed
will be that of the current day. In 7 Day mode only a single day number
will be displayed, in 5/2 Day mode either 12345 or 67 will be displayed.
To go through the available events press and release the NEXT
button. While each event is on display, it may be altered as required.
Selecting an event time
Press and hold down the + or - buttons
to change the event time in ten minute
steps. Press and release to change by
one minute.
Selecting a heating temperature
Press and release the button to raise
the HEATING control temperature by
0.5°C (1°F), or press and release the
button to lower the HEATING control
temperature by 0.5°C (1°F) . Press and
hold down these buttons to make larger
changes to the control temperature.
Selecting a cooling temperature
Press and release the button to raise
the cooling control temperature by 0.5°C
(1°F), or press and release the button
to lower the cooling control temperature
by 0.5°C (1°F).

Selection of an 'OFF' event
If there is a demand to turn 'OFF' rather than turn down the heating or
turn up the cooling, for example during unoccupied periods, an 'OFF'
event can be selected.
Selecting a programmed "Off" event for heating: use the button to
lower the heating set temperature to its minimum value which is "Off",
the characters "Of" will replace the heating control temperature.
Selecting a programmed "Off" event for cooling: use the
button to
raise the cooling set temperature to its maximum value which is "Off",
the characters "Of" will replace the cooling control temperature value.
When all events for the day(s) on the
display are as required, press DAY to
show the following day's events.
The display will appear similar to one of
the diagrams on the right, depending
on whether the HP75 has been set up
for 7 day or 5/2 day mode.

NOTES ON SETTING EVENT TIMES
7 (Sunday)
(Assumes unit is in 6 events/day mode)
If, during the event checking and setting procedure, no buttons are
pressed for more than two minutes then the HP75 will return to RUN
mode automatically. If this appears to have occurred, it is advisable to
re-check the program to ensure that it is as required.
When setting event times and temperatures it is not possible to set
event times out of chronological order.
Event 1 may be set at any time from 0:00AM to 11:59PM (but would
normally be in the morning).
Event 2 may be set at any time between event 1 and 23 hours, 59
minutes after event 1.
If the event time being set is moved past midnight into the following day
then the number of the following day will blink.

THERMOSTAT MODE
The HP75 can be converted to control either heating or cooling, (not
both), at a constant user selected temperature by selecting "Thermostat
mode". To do this, press and hold down both
buttons until the
display changes to that shown in fig. 6. When entering thermostat
mode the default setting is heating only, with a default temperature of
8°C (46°F), this can be changed as required by pressing either or
until the require temperature is displayed.
To control at a constant cooling temperature (heat off), press the 'SEL'
button to select 'COOL', the temperature will be shown as 28°C (82°F)
(fig. 6a) use the and buttons to select the required temperature.
When in thermostat mode if "OFF" is selected by means of the
button, both heating and cooling are turned off.

holiday period of 00 days. Use the + or - buttons to set the number of
days required, in the range 1-99 days. If the number of days is left at 00
then the unit will return to normal at event 1 the following day. When the

BATTERY MAINTENANCE
It is recommended that high quality alkaline batteries are used.
New batteries will provide the power for switching the outputs on and
off for approximately 2 years. When the batteries' voltage drops to the
minimum level needed to maintain operation, a battery symbol will
blink in the display (See Fig.12). When this symbol appears both
batteries should be replaced with high quality alkaline cells. Operation
will continue normally until the 15th midnight after the symbol started
blinking and then the unit will switch off all outputs and shut down with
just the time and the blinking battery displayed. While the battery
symbol is still blinking, the old batteries may be removed and new
batteries placed in the sleeve and inserted within one minute.
Internal circuitry will maintain the user set program during this period.
